J. J. CURELLO RADIATOR SUPPORT 2 Sheets-Sheet 1 Filed Dec. 25, 1924 Patented June 10, 1930 UNITED STATES PATENT OFFICE JOHN J. CURELLO, on NEW HAVEN, CONNECTICUT, ASSIGNOLR- 'ro THE a a o MANU- I rAoTURINc COMPANY, on NEW HAVEN, CONNECTICUT RADIATOR SUPPORT Application filed December 23, 1924. Serial No. 757,679.

This invention relates to radiators for in ternal combustion engines, and more particularly to a novel means for supporting sucha radiator upon the chassis orframe of a vehicle or the like in such a manner that the radiator will be relieved from the strain incident to road shocks or the like when; the vehicle is in mot-ion, and thus the dangerof leaks developing in the tanks or cooling passages of the radiator from such shocks will be reduced to a minimum. At the same time I contemplate the provision of such a connection between the radiator proper and the frame of the vehicle that '15 the radiator tanks will not have to be perforated or pierced, but on the contrary a strong and secure connectlon is made without such operations, and thus there is obviated the danger of radiator leaks dey veloping about such perforations, as is very often the case when such openings aremade as is usual with the methods of construction commonly employed.

One object of my invention is to provide a resilient or yielding support between the chassis of a vehicle and the radiator to lessen the shocks received by the latter due to vibrations and road shocks occurring in the chassis.

Another object of the invention is the provision: of a spring or resilient support for supporting the radiator of a motor vehicle from the chassis so that the radiator will be permitted. movement to some extent independently of the chassis, and thus be relievedto some extent from shocks occurringin the latter.

A still further object of my invention is the provision of the novel method of securing the radiator proper to the supporting member so that a firm connection is ha'd,and-at the same time. no bolts or fastening members are passed through the tanks of the. radiator around which leaks are apt to develop.

'Ilo-these and. other ends: theinvention consists in the novel features and combination of partsto be hereinafter described and claimed.

In Fig. 1 of the drawings, I have shown an automobile radiator of conventional form comprising the upper and lower tanks 10 and 11. between which extend the cooling water passages 12. The chassis or frame of the motor vehicle upon which the radiator is adapted to be supported is represented by two longitudinal frame members 13 and 14 which in the form shown are channel shaped members, although their particular form is not important in connection withmy invention. The longitudinal frame members of the chassis are generally connected by transverse frame members, one of which is shown at 15, and

bolts against displacement.

give much better service if a resilient or cushioned support is provided for it, so that it may be permitted a certain amount of up and down movement independently of the chassis of the vehicle. As shown in Figs. 1 to 3 of the drawings, one means which I have employed for providing such a support consists of securing to the rigid transverse member 15 a radiator supporting saddle bar ormember' 16,, which is of the proper thickness ofinetal to possess a certain amount of resiliency. This resilient or flexible saddle bar is spaced fromthe transverse member 15 by ,means of end blocks 17 so as to provide for up and down movements of the cushioned saddle bar member, the greatest of which movements will naturally take place at or about the central portion thereof. The member 16 is secured to the transverse member 15 adjacent its ends by means of the bolts 18 which pass through openings 19 and 20 in the members 17 and 15 respectively which are slightly larger than the bolts themselves. It will be apparent that when the member 16 moves upwardly or downwardly, due to shocks transmitted to it through the vehicle chassis, the length of this member will be somewhat altered, and the slight amount of play permitted between the bolts 18 and openings through which it passes will be suflicicnt to allow for these movements.

The lower surface of the tank 11 of the radiator normally rests upon the resilient saddle bar 16, and it is, of course,'necessary to provide a fixed connection between the radiator and this member. It is also desire able, however, that the connection be made at spaced points, and also at points spaced from the bolts 18 so-that the up and down movement of the members 16 will be freely permitted without danger of consequent damage to the radiator through strain transmitted thereto. To provide such a connec tion, I secure to the cross members 16 a pair of channel members 21 and 22 in such a manner that the bases 23 and'24 of these channel members lie below the member 16 and are provide'dwith openings'to receive the bolts 18, so that the bases 23 and 24 of the channel members will be secured by these As shown in Fig. 2, the base of each channel member may also be provided with an opening 25 into which is punched a boss 26 from the saddle bar 16 to provide an additional connection between these members.

The sides of the channel members 21 and 22 are designed to embrace the lower tank of the radiator, the lower corners of these sides adjacent the securing bolts being cut away, as shown at 27 and 28, so that the connection between thesides and the bases of the channel members will be at an appreciable distance from the securing bolts 18.. It

will be apparent that, if such an expedient is not resorted to, the connection between the transverse member 15 and the radiator through the bolts 18 and channel members would be too rigid to permit the desirable cushioning effect of my support.

The sides of the channel members 21 and 22 are provided with series of openings 30 and 31, through which solder may be flowed to solder the lower tank securely to the channel members so that the radiator will be fixed rigidly thereto. The sides of the channel member 21 are somewhat shorter than those of the channel member 22 in order to provide a clearance for the water outlet 32 located in the form shown at this side of the radiator. In'order that the up and down movements of the saddle bar 16 will not be interfered with, the lower tank of the radiator is oflset adjacent its ends, as shown at 33 and 34, so that the bottom of the tank at these points is spaced from the upper surface of the member 16. It will be apparent that at these points the saddle bar 16 is held rigidly against any movement in a vertical direction, and it is, therefore, essential to provide at these points a clearance space between these members and the radiator tank.

As shown in the sectional view of Fig. 4, the resilient supporting saddle bar 16 lies between the bottom of the lower tank 11 of the radiator and the bottom piece 2 1 of the channel member. Throughout the greater part of the width of the radiator the bottom of the tank will'rest mostly. against the member 16, as shown in this figure.

If desired, the bottom of the radiator tank 11 may be constructed as a flat plane surface and the offsets 33 and 34 omitted, and in such case, clearance between the saddle bar 16 and the bottom surface of the tank may be provided at the ends by blocking up the tank from the saddle bar by means of two or more spacing members inserted between the bar and the bottom of the tank. Substantially the same result will be accomplished in this way, as provision will be made for vertical movements of the radiator with respect to that part of the saddle bar "adjacent the bolts 18 and 20.

In the modification shown in Fig. 5, the cushioned saddle bar 16 is provided with offset or bent portions 36 and 37 which are designed to take up the changes in length of the member 16 which occur during its up and down movements, so as to permit a certain amount of elongation of the saddle bar under strain. In this instance, the bolts 18 may be fitted closely to the openings in the chassis member 15, and no play or movement allowed between the bolts and the chassis members. In this form of my invention the bottom portion of the channel member is shortened so that it does not extend outwardly to be secured by the bolts 18, the

channel members being held in place by means of theperforations 39 into which are struck or punched the bosses 40 from the members 16. I may, if I desire, use the ordinary carriage bolts 41 provided with the squared upper ends 42 which are designed to be inserted throughsquared openings in the ends of the members 16, so that these bolts will not rotate after being put into place.

As shown in Figs. 6 and 7, I may secure the channel members to the radiator tank by displacing the Wall of the tank to provide a series of recesses 43 and punching out portions of the sides of the channel members to provide bosses or projections 44 to enter these recesses. The perforations 45 are provided within the bosses through which the solder may be flowed to make a secure soldered connection between the tank and channel members, as heretofore explained.

It will be apparent that, by supporting the radiator in the manner shown upon a resilient or cushioning supporting member instead of supporting it directly from the vehicle chassis, I provide a resilient or cushioned support for the radiator which will clearly lessen any shocks transmitted thereto, and by securing the radiator to the resilient member at spaced points and at points spaced from the fixed ends of this member the movements of the resilient member will have no harmful effect upon the radiator, but, on the other hand, the life of the latter will be clearly prolonged and its service improved.

In Fig. 8 of the drawings, I have shown a somewhat different method of mounting my resilient support upon a vehicle chassis. In this instance, the longitudinal frame members 46 and 46* are connected by the rigid transverse member 4E7. Upon this member 47 are secured brackets 48 and d9, and the resilient supporting member 16 is in this instance secured upon these brackets in the same manner as upon the transverse member 15, as shown and described in connection with Figs. 1 to 7 of the drawings. It will be understood, however, that the specific manner of mounting my improved support upon the chassis will depend to a large extent upon the make of automobile, as the chasses of various makes of cars differ to some extent in construction. The method shown in Fig. 8, for instance, is one in the spirit of the invention and within the scope of the appended claims.
